Thread: Sherwood 13 inch Segmented Spiral-Head Thicknesser

There are a number of design improvements on this new machine that address the causes of snipe. These includes a heavier duty 4 post carriage support, the segmented cutter-head, wider feed rollers, a granite plattern, and a longer and more robust design within the infeed and outfeed tables. Nothing more to add on this subject.

Stewie;

Stewie do you work for Timbecon?

As all your posts appear to be advertising the new machine and/or copy/paste direct from the product brochure rather than reviewing it for what it is...

If Timbecon send me a unit, I'll review it for 'em and post the review back on here.

tonzeyd; no I do not work for Timbecon. I paid full price for this machine, and no discount was offered to shill it to other prospective buyers. If your wanting a tool review, look elsewhere.

The first two of those do literally nothing to affect snipe, the third one is highly questionable but I'll concede that it *might*, the fourth one is for vibration damping and longer wear and will perform no better for snipe than any other rigid material of equivalent flatness, be it steel, aluminium, or 32mm MDF.

Sounds like the greatest improvement they made was to their marketing department...

Snipe in lunchbox planers is also caused by the cutterhead flexing when the workpiece first passes under the infeed roller and again when it exits under the outfeed roller, not just from tables flexing. A heavy duty four post carriage support may well do something.

Wow, never realised they were so flexy...no wonder they call them lunchboxes

I have two H&F thicknessers, the first was a four post with two height adjustment screws one on each side and a clamping system. If you don't clamp it really you get bad snipe. The second is the new T13S which has no posts just four screws, one in each corner, no clamp and with no clamping almost no snipe if the two tables are correctly adjusted and you support any long boards.

Interestingly the new machine is much lighter so it must also be better designed and built.

I may be confused but all the machines in posted pics.
All look to have 4 carriage posts.
Could someone please enlighten me

Cheers Matt

You're the 1 calling yourself the machine doctor.

*You're

Yes I do call myself that and the people at work will confirm it, but I'm not used to machines that you can pick up and move; the smallest thicknesser I've used weighs about a ton and certainly doesn't flex when you feed timber through. I'll leave you to your toys.

Although Stewie did not start this thread to discuss snipe on his new plane (maybe it snipes and maybe it does not, this has not been confirmed yet) in the interest of getting the thread somewhere back to sensible, here is a link to a very good article and video which explains snipe in small planers coming from the cutterhead raising and lowering as the in- and out-feed rollers ride over the end of the workpiece. It gives strategies to minimise the problem.

Maybe Stewie could do a trial run to find out how much snipe is really there and post the results here. While you will never totally eliminate snipe particularly in a small planer it would be interesting to get some feedback on how much difference the improvements in this Sherwood model have made.

Anyway here's the link: https://woodgears.ca/jointer/planer_snipe.html

I have a 60+ yearold Jeffwood Thicky with conventional 2 blade set up. To reduce snipe my out feed table is a little higher that the machines table. It doesn't totally stop it but reduces the incidents a lot

Hi Rod

What you are doing will not eliminate snipe, and may create a similar problem owing to the outfeed table being higher. I am assuming that it is higher to compensate for it dropping when the weight of the board rest on it.

All tables need to be flat and coplanar throughout. At least that removes the snipe caused by the board tipping up or down and into the blades.

The easiest simple fix is a long board attached through the machine. It needs to be flex-free. A few layers of Ply or MDF may do it, and I'd add a layer of melamine on the top.

I have used a few machines, diffrent makes, and the tables all flex (the tables are built for transport, and for this reason they are hinged and built lightly). Either reinforce them - as in my photos - or by-pass them.
