I thoroughly enjoy your podcast, so thank you for all that you do. What is you opinion on dog holes in the workbench? If you use them, how?  Include favorite accessories. Thank you again. Josh

I’m in the early stages of designing/building a dining table made from quarter sawn ash (just purchased a bunch of 4/4 lumber). I’ve designed the table based on a picture my wife showed me for inspiration.

It is a trestle style table in which the two uprights are 16” wide by 4” thick. The ‘feet’ or ‘bases’ will be 30” wide by 6” thick, while the ‘trestle tops’ which support the table top will be 34” wide by 6” thick. The thickness of these trestles concerns me both in how much they are going to weigh, and how much material they are going to require.

I’ve read about the strength of lock miter joints and am intrigued by the idea of glueing up a panel and essentially creating a hollow ‘box’ for the upright portion (boards would run vertically). I’ve read that these types of joints are very strong and I imagine they would be sufficient for this application (correct me if I’m wrong). I also like that they may give the appearance of using ultra thick 4” lumber.

My question is whether you believe there will be enough wood movement in these hollow uprights to cause concern, as they will be constrained by both the feet and tops of the trestles? I just don’t have enough anecdotal experience to have a good feel for how much movement is likely to occur. Are there any good “rule of thumbs” regarding how much movement is expected to occur? I know there are a million variable (humidity swing, plain sawn vs quarter sawn, species, etc.)

Thanks for your consideration and response to my question! Evan

I recently upgraded my benchtop planer from a straight-knife Ridgid model to an Oliver 10045 with a helical head. I was excited by all the reviews raving about the ultra-smooth finish, but I've been disappointed. I'm getting noticeable scalloping from the inserts, even after removing them all, thoroughly cleaning the inserts and seats, and properly re-torquing them with a torque wrench. It's still requiring way more sanding: starting with 80 grit (which takes forever to remove the scallops), then 120 grit (longer than with my old planer), before progressing normally. My old straight-knife Ridgid needed far less sanding overall.

From my research, this scalloping seems pretty normal with standard helical heads. I've heard one temporary workaround is to run boards through 2-3 extra passes at the final thickness setting, offsetting or skewing the board slightly each time to better overlap the cutter paths and reduce the scalloping (making sanding easier). I plan to try that soon.

I was saving for Grizzly helical-head jointer and planer upgrades, but now I'm worried about the same increased sanding time.

A few questions:

Is noticeable scalloping typical with most helical-head planers, including Grizzly and Oliver models?

I've read that the Silent-Power spiral cutterblock on the Hammer A3 series produces a much smoother surface with minimal ripple or scalloping, requiring far less sanding than standard helical heads. Is that your experience?

I'm now leaning toward a Hammer A3-31 combo machine down the road. I wanted separate jointer and planer for better workflow and time savings, but I can't deal with doubling my sanding time. For those with 12" combo machines like the A3-31, do you ever regret not going for a 16" model (e.g., A3-41) for the extra width capacity? Thanks for any insights. You guys are my go-to for real-world tool advice! Jeffery Hiughes

First let me say how much I appreciate your podcast for it's practical woodworking advice. I have a comment and question. The comment is in response to the podcast of yours that I listened to today regarding the future of reclaimed wood. I wonder if the future will include recycled wood products designed with the look, feel, and workability (or close) of natural wood? Just a thought. Anyway, here is my question: My workshop is an unheated 3rd bay of a garage. It is not insulated. I use a shop vac in conjunction with Home Depots dustopper for dust collection. Better than nothing but not perfect. The cold is a deterrent to want to work out there and am wondering about safe budget conscious heating options. What are the safety considerations to take into account (dust, fumes, other?) I have a Mr. Buddy Propane Heater that has some nice safety features but don't know if it's safe to use.  Do you have any recommendations on how to safely heat up a workspace?  Thank you.  James Aydelotte (aid-a-lot)
