  1. Steve, As Jeff stated you only need the larger main with multiple tools running at the same time. Most of us are in a single person shop only running one tool at a time so with blast gates you only need to worry about the CFM required at one tool. 350CFM is the minimum for collecting chips, bump it up a couple hundred CFMs for the dust you can see and another couple hundred for the dust you can't see (but your lungs can). If you are going to do option 3 then the 1029 is a better deal. The big difference is the output immediately necks down to a 5" flex hose and then exhausts into a
  2. Steve, Not sure why you can't do option 3 with the Grizzly the exact same way as the HF or any other DC blower. As stated the less hoses/connections the better. As previously stated the HF is not even close to the performance of the Grizzly. Looking at the attached chart you will see the lower performing version of the Grizzly 2HP (G1029) is second from the top. The G0548 will outperform the 1029. The HF is second from the bottom. Even with the mod it not perform as well as the Grizzly. The duct size is important in a system design. Some cyclones have 7 & 8" inlets but an 8" duct
  3. Steve, There is no question the Grizzly is the better choice. Stated CFM is far overstated in both cases as with all single stage DCs. The HF claim makes it seem close but it is impossible for the original 10" impeller to outperform any 1 1/2HP DC with 11" impellers, yet alone come close to the Grizzly. The Grizzly is also a stretch but with a 12 3/4" impeller will outperform the HF with the 12" Rikon upgrade (Actually only 11 3/4"). Also, the Rikon is only 3 1/4" tall where the Grizzly is about 4" tall. So the larger diameter provides more static pressure and CFMs and the taller im
  4. Prov, No war starting, but DC topics usually have a lot of opinions and subjectivity (not too much in this discussion). Bottom line is what do you want from your DC? To feel air moving through an opening and the ease to make that happen. Or to move the most air possible with the equipment you have. There are countless numbers of people that saw a YouTube guy use undersized pipe on his DC and it picked up chips so they copied it and then went on to profess themselves as experts of using undersized pipe and how great it works! (all untested of course). Do they move air? Will they pick u
  5. Jfitz, I had the same unit several years ago and the unit has been tested by wood magazine among others. So fan curves are available to get performance numbers. Generally, 1.5HP-2HP units have 11-12" impellers (HF is the exception with 10") will get choked down with 4" ducts and they can't produce enough CFMs in 6" ducts to maintain a high enough velocity, so 5" ducts are the best balance. Carl
  6. prov, With most 1.5HP-2HP units and small runs you are better off using 5" HVAC ducting. Out of the box with 4" ducting you will be starting with ~575CFM and reducing it with every foot of 4" pipe you add. With 5" you will probably start ~675CFM. You will have ~50% more duct area with 5" (6" is too big). With your short runs the cost is only slightly more. Here are some sources for material (whatever size you use): Blast gates and hose are available here 5" Aluminum ~$12 http://www.blastgateco.com/Cast-Alum...last-Gates.php Wyes here ~$13 http://www.simplyplumbing.com/27013-sm
  7. I will have to lean on the side of seeing what happened after the fact vs. preventing anything. If they know there is a cam they put their head down cap on/hood up and proceed. Or... I live in a town across from the library and a retirement home and next door to several townhouses. At 5 in the afternoon a girl and her mother were walking on the other side of the street from my house. The girl ran across, followed by her mother walking and the girl stole a package from amazon (a 12" drill bit extension!!) from my porch. They both walked to their car across the street and drove off. The si
  8. I would not waste your time or money on the blanket angle. As others have suggested you need mass to absorb sound. The reason I say pass is I was in a condo that faced a busy road and my son's room would get some loud car and truck noises in his room (the background din was not an issue). I bought specialty sound blankets used for temporary sound recording studios to cover the windows. Because they were set sizes I was able to double the blanket material over the window. The blankets were very heavy ~5-10x the weight of a moving blanket. Bottom line, there was an improvement, but not sign
  9. Grant, I have looked at doing exactly that modification. It appears very easy (just haven't order the material.). It looks like removing the fence and replacing with a plate to cover the 4 mounting screws (~4"x5") from the top and an extrusion to mount on the middle of the plate. I look at the Mitsumi extrusions (~1x3?) for a milled length and I think it was about $25-30. The plastic runner on the back of the current fence could be reused. Hope that helps. Let us know what you do. Carl
  10. An alternative idea would be to sell your Shop Fox on CL $50-$100 and add that to what you would spend on a HF DC and buy just about any 1.5HP DC on CL. As you can see from the attached chart, due to its undersized impeller the HF performs below all the tested 1.5HP DCs and just above a typical 1HP DC (like yours). Since both tools are stationary and have short runs you can switch to hard ducts (eliminate all flex hose) which will provide less resistance, resulting in better performance. Also eliminate any hard 90s like the one attached to your current DC. A separator is a great idea,
  11. You could definitely go with the HF DC, which I almost did for a temporary solution (shop is being torn up and rebuilt) until I found this review http://www.portercable.com/uploads/PCD/Documents/News/182DustCollectors.pdf (look at the chart on page 67) which shows every other 1.5HP dc outperforming the HF 2HP (central machinery) DC due to its undersized 10" impeller (most 2HP have 12"+ size impellers). So I instead went on CL to look for a 1.5HP DC, which there is never a shortage of units for sale! I can get a used 1.5HP DC with better performance on CL for the same price as a new HF unit
  12. Leros, Unless you modify your HF with the 12" rikon impeller (up from the installed 10") you will not have enough power for your shop. There is an old DC review that shows the results of putting that small of an impeller on a DC http://www.portercable.com/uploads/PCD/Documents/News/182DustCollectors.pdf It basically shows the stock HF 2HP DC is outperformed by every 1.5HP DC tested due to the smaller impeller. Unless you go to a 3hp blower or higher there really is no need to use 6" ducts. 5" is optimum for the 1.5-2HP DC. If you did the upgrade, mounted the blower on
  13. Rodger if your already have the delta why not do something like this: Hope this helps...Let us know what you do. Carl
  14. @Vic - love the floor! I can't believe that is plywood. Can you tell me more about what is underneath, how you attached, how many coats of shellac, etc... Thanks, Carl
  15. Colin, As Jfitz stated you don't say a lot about what you have or need. Why would going from brand A 1HP DC be an improvement over brand b 1HP DC? (It could but not likely of any significance). As Eric stated these smaller DCs are not going to get the fine dust. It is also worth looking at a comparison of what these machines are capable of doing so see the chart in this old review http://www.portercable.com/uploads/PCD/Documents/News/182DustCollectors.pdf You will see your current 1HP unit at the bottom of the 4" Port Performance curves (below the minimum performance line).
