Thread: blocks

I made some enquiries and found that bakelite is still available from any plastics supplier, check your yellow pages on line. I use redgum at the momemt and I think may too. He told me what he used last week and I have since forgotten. Lignum Vitae is another good material and available from your local bowling club when the bowler are not looking

Don't look for Lignum Vitae at the bowling club. It hasn't been uses in bolws for at least 60 years probably closer to 80.

Gooday.

I used Red Gum as Iain said in my old saw that had blocks.

In my old saw that I still use I made a bearing carrier that works really well.

I was looking at a US forum on the same subject and they bagged bearings something fierce. I am looking for it now as I cannot recall what they thought the problem was. I thought it would have to be an improvement.
Neil, lignum vitae, there wood (?) have to be some old hand me downs out there at the bowling clubs still, and, how do you tell the difference between lignum vitae and composite bowls. To me they all look alike?

I bought a 14" bandsaw from Carbatec about 4 years ago. Made in Taiwan, for about $600. It came with so called "cool blocks" made of some sort of high density plastic. Apart from the odd new blade,it has'nt missed a beat. The blocks are still as good as new.
The saw,(and blocks available separately $49) are on p.21 of Carbatecs current cattledog.
Obviously being just a hobbyist my machinery would not work the hours, or as hard as Robbos and other Professionals but it does all I want of it. Incidentally I never slacken off the blade between uses, and I have yet to break one. Hidden nails are my biggest bugbear.

I believe the cool blocks are bakelite and can be purchased for about $25 per metre in 3/8" square. John, what you need is one of those little u beaut stud finder/voltage detector/metal detector thingo's for about $40 from Jaycar in Ringwood. Three blades would pay for it

Gooday.

Was it dead wood?

I have replaced the Bearings 3 times in 15 years.

Ironbark, silver birch, LEADGUM

If the blocks are made of plastic they maybe be made of DELRIN. Its a very tough machinable plastic.
If you decide to make blocks of Phenolic Resin (bakelite) be aware that when cutting, filing or drilling the stuff it gives off toxic fumes and the saw dust is carcinogenic.

I bought some Delrin blocks from Academy Saws in Sydney (I think) several years ago & they certainly improve the running. I think the material for 'cool blocks' would be delrin, not bakelite.

Thanks to all for all the info. I have got hold of some delrin and bakelite 12mm square section by a metre long for about $15, including postage, each from a couple of plastics distributors in Newcastle and Sydney. Given the advice of Glen about the carcinogenic stuff I think I will be using the delrin. Can any body suggest what to do with a metre of bakelite?
