I have a fixture table with 16mm holes on 2" centers from another manufacturer and my top is only 1/4" thick. Is it possible to use the ToothBlock Kit with this table. I don’t think the Tacking Bolts that you use with that fixture will work on my table top that is only 1/4. Is that correct? Is there another way I can still make that ToothBlock fixture work with my table? Thanks -Steve ---

it would work, you would need to use a bunch of spacers or washers to take up the slack in the extra space in the bolts the holes on the 1/4" tables typically don’t have a chamfer on the back side, but it still generally works with the bolts ---

I too have a 16mm table on 2" centers… which is 1/4" thick. (from CertiFlat) re: the ~3/4" spacers I need to fabricate to be used with the Toothblock Kit. Is it practical for the ~3/4" spacers be used “top side” on the table ? Or just “underside” of table, or both ? Just trying to understand what makes sense, should I go down this path. Thx. ---

Yes you can use your 1/4 table top with the correct spacer. It’s preferred to put the spacer on the top next to the head of the tack bolt. > **[Tacking Bolt Spacer - 3/4" Diameter](https://fireballtool.com/products/dragon-spacer?_pos=1&_psq=Spacer&_ss=e&_v=1.0)** > > These spacers are designed when you have table system with 3/4" diameter holes, but the thickness of the table is less than 1".

Those spacers are only for the Fireball 3/4" system, if you’re using another system you’ll have to use some washers that fit 5/8 or 16mm bolts ---

I think the good news is that you can still use the toothblock kit. I did a dumb thing when I got mine and didn’t buy the tacking bolts, but I was still able to use the blocks and washers. This isn’t the best idea, but it worked for me: while I was waiting for the order for tacking bolts to come in, I used some 5/8-11 bolts through the table and just tightened a nut onto the underside. Those tacking bolts are really awesome, though. They’re totally worth having even if you have to weld a washer to them to make it a little more convenient. ---

I just received my tooth blocks and tacking bolts, found that on my table [3/8 thick] that at least one hole is too thin so I will get some washers to use all the time. It took only 3 days from order to receiving my order keep up your good work. ---

That’s really strange. I’ve got a 3/8" thick table and the tacking bolts work just fine on the tooth blocks. Are you using them with something else? ---

The table is cast and not finished on the bottom. It was only the one hole when I was checking the fit, not a real issue. It could be only the one hole on a 2 foot by 6 foot table, I will not try to check all the holes just use the washers. ---

Sounds like it’s not actually 3/8" thick. You might even consider getting it exchanged if it’s new and supposedly 3/8" ---
